XENBUS: Device not ready - Guest virtual machine issue

Hi,

We have created Guest Virtual machine using the following command.

sudo /usr/sbin/xm create /opt/VM_DIR/3/images/deployment.0 && sudo /usr/sbin/xm sched-cred -d one-3 -w 128

The virtual machine succefully booted and it is in the running stage. but when i try to open the virtual machine console to login. i am getting the following error message and also unable to see the graphical console.

error message is …
XENBUS: Device not ready: device/vbd/51713
Creating device nodes with udev
Creating device nodes with udev

deployment.0 file content is

name = ‘one-3’
#O CPU_CREDITS = 128
memory = ‘256’
kernel = ‘/boot/vmlinuz-xen’
ramdisk = ‘/boot/initrd-xen’
root = ‘/dev/xvda2’
extra = ‘ro noapic acpi=off console=tty1’
disk =
‘tap:aio:/opt/VM_DIR/3/images/disk.0,xvda,w’,
‘tap:aio:/opt/VM_DIR/3/images/disk.1,xvda1,w’,
]
vif =
‘mac=00:17:31:6E:EA:DF,bridge=xenbr0’,
]
vfb = ‘type=vnc,vnclisten=127.0.0.1,vncdisplay=9999’]

We are using openSUSE 11
